Appsignal Sourcemaps

This ruby gem uploads (private) sourcemaps to Appsignal using the Sourcemaps API.

Installation

To start using this gem, add it to the Gemfile of your application:

source 'https://rubygems.pkg.github.com/drieam' do
  gem 'appsignal-sourcemap'
end

After running bundle install you should enable the gem by adding upload_sourcemaps: true to your config/appsignal.yml file:

default:
  upload_sourcemaps: true

Also ensure that your Rails.application.config.asset_host is setup correctly since that is used to define the full URL of the assets. The gem then uploads the sourcemaps after the assets:precompile rake task. It searches for all .map files within the Rails.public_path directory.

Heroku

When building on heroku, make sure you set the revision based on the SOURCE_VERSION environment variable. This variable is set during the build phase and will be equal to the HEROKU_SLUG_COMMIT revision on runtime. Note that you should have heroku dyno metadata enabled.

default:
  revision: "<%= ENV['SOURCE_VERSION'] || ENV.fetch('HEROKU_SLUG_COMMIT', 'unknown') %>"

Publishing a new version

The publish workflow listens to a new release in GitHub.
